zylkene plus 225mg capsules for adult cats

Ease. Daily support for calm when life feels unsettled.

A natural supplement containing alpha-casozepine — a milk-derived protein peptide — selected to support emotional regulation during periods of change or ongoing tension. Used to help maintain calm from within, without sedation or behavioural suppression.

Zylkene Plus is introduced when routine disruption, environmental change, or persistent stress begins to affect how a cat experiences daily life.

Important packaging note

This product is packaged for dogs (10-30kg weight range shown). This is the formulation used for cats under veterinary guidance, as the lower-dose feline-specific product is not clinically effective. You will receive dog packaging—this is correct and appropriate for your cat.

What this supports

• Calm during periods of change
  Supports cats through situations such as household disruption, visitors, new animals, or relocation — particularly when change unfolds over days or weeks rather than moments.

• Emotional regulation without sedation
  Helps support natural calming pathways, allowing cats to remain alert and responsive while feeling less overwhelmed.

• Ongoing support when stress persists
  Suitable for daily use during periods of recurring or sustained tension, with reassessment as circumstances settle or change.

How to use this supplement

Administer once daily. Capsules may be given whole or opened and mixed into food.

Use is typically considered during periods of ongoing change rather than single events. Duration should be guided by observation and reviewed as circumstances evolve.

What this supplement is — and is not

This is daily support for cats experiencing environmental or situational strain. It does not cause drowsiness or sedation.

It is not a treatment for behavioural disease, aggression, or acute anxiety. Significant or escalating behaviour changes warrant understanding before relying on supplementation alone.

When to pause and seek guidance

If stress-related behaviours persist, intensify, or are accompanied by changes in appetite, elimination, or social interaction, a veterinary-informed conversation is recommended before continuing support.
